Diamond coating should be selected for processing graphite tools. It has the advantages of high hardness, good wear resistance, and low friction coefficient. At this stage, diamond coating is the best choice for graphite processing tools, and it can best reflect the superior performance of graphite tools; The advantage of diamond-coated cemented carbide tools is that they combine the hardness of natural diamond and the strength and fracture toughness of cemented carbide; it can increase the service life of the tool by nearly 10-20 times.

Classification by smelting method
Converter steel: It is a steelmaking method that blows air or oxygen into molten iron, rapidly oxidizes C, Mn, Si, P, S, etc. in molten iron, heats up by heat released when oxidized, and does not rely on fuel heating. Converter steel is currently the main steelmaking equipment because it saves fuel.
Open hearth steel: open hearth steel is burned by the combustion of fuel (gas or heavy oil) to melt the charge and raise the temperature of the molten steel. Oxygen in the furnace gas and iron ore are added for the oxidation reaction. As the open hearth steel consumes a large amount of fuel, it has gradually been eliminated. China’s 99 years Flat-furnace steel has dropped to about 2%, and the open-hearth furnace will be completely eliminated in 2000.
Electric furnace steel: A method of making steel using electric energy as a heat source. Electric furnace steel mainly produces high quality and high alloy steel.
